Short answer: For complex operations, you might want to implement batch command execution. Multiple commands can be grouped together, and executing or undoing the entire batch can be done in a single operation.

Real-world example (ShopNest)

Say this in the interview

1. Define — one clear sentence (the short answer above).
2. Example — relate it to a project like ShopNest or your real work.
3. Trade-off — when you would not use it.
